Search for lepton flavor violating τ- decays into ℓ-KS 0 and ℓ-KS 0KS 0

Olivier Schneider, Aurelio Bay, Remi Léandre Albert Louvot, Jian Wang, Chao Wang, Vladislav Balagura, Ji Hyun Kim, Xiao Wang, Jing Li

We have searched for the lepton-flavor-violating decays τ- decays into ℓ-KS 0 and ℓ-KS 0KS 0 (ℓ=e or μ), using a data sample of 671 fb-1 collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. No evidence for a signal was found in an ...

Measurement of cross sections of exclusive e+ e- → V P processes at sqrt(s) = 10.58 GeV

Olivier Schneider, Aurelio Bay, Remi Léandre Albert Louvot, Chao Wang, Vladislav Balagura, Ji Hyun Kim

The cross sections for the reactions e+ e- → φ{symbol} η, φ{symbol} η′, ρη, ρ η′ have been measured using a data sample of 516 fb- 1 collected with the Belle detector at the KEKB asymmetric-energy e+ e- collider. The corresponding values of the cross secti ...

Tight bounds on the AUH codes

Ali Kakhbod

In this paper we consider the class of anti-uniform Huffman codes and derive tight lower and upper hounds on the average length, entropy, and redundancy of such codes in terms of the alphabet size of the source. Also an upper bound on the entropy of AUH co ...

A mealy machine with polynomial growth of irrational degree

We consider a very simple Mealy machine ( two nontrivial states over a two-symbol alphabet), and derive some properties of the semigroup it generates. It is an infinite, finitely generated semigroup, and we show that the growth function of its balls behave ...

Non-binary LDPC codes and EXIT like functions

In the first part of this thesis we are interested in the asymptotic performance analysis of Non-Binary Low-Density Parity-Check (NBLDPC) codes over the Binary Erasure Channel (BEC) decoded via the suboptimal Belief Propagation (BP) decoder as well as the ...

Search for lepton flavor violating τ- decays with a KS 0 meson

Olivier Schneider, Stewart Cole, Chao Wang, Tagir Aushev, Lei Zhang

We have searched for the lepton flavor violating decays τ- → ℓ- KS 0 (ℓ = e or μ), using a data sample of 281 fb-1 collected with the Belle detector at the KEKB e+ e- asymmetric-energy collider. No evidence for a signal was found in either of the decay mod ...

On Average Throughput Benefits and Alphabet Size in Network Coding

Christina Fragouli, Emina Soljanin

We examine the throughput benefits that network coding offers with respect to the average through- put achievable by routing, where the average throughput refers to the average of the rates that the indi- vidual receivers experience. We relate these benefi ...

On Average Throughput Benefits and Alphabet Size in Network Coding

Christina Fragouli, Emina Soljanin

e analyze a special class of configurations with h sources and N receivers to demonstrate the throughput benefits of network coding and deterministic code design. We show that the throughput benefits network coding offers can increase proportionally to \sq ...
